The typical sight of homeless people is very common especially in metropolitan areas. We are accustomed to see people living on the streets and most of us simply accept this situation since we are all trapped in our own spheres of life.
Consequently, it is really refreshing when someone is able to give us a reality check by reflecting our behavior. Watch this brilliant social experiment and feel enlightened within a minute. The video was made by the Pillion Trust, an UK based charity organization.
However, you might want reconsider your attitude towards homeless people since poverty has been rising lately and maybe one day it is you living on the streets (hopefully not).
